Abstract: Mixtures of di- and poly-glycols are produced by diluting with water the distillation residue obtained in the production of ethylene glycol from ethylene oxide and water, and removing from the diluted residue the impurities which separate.  The mixture obtained contains mainly di- and triethylene glycol, the impurities removed being polymers which precipitate on addition of water and inorganic salts which separate when the water is subsequently distilled off.  The glycol mixture, which initially has a high pH, may be used, after neutralization and bleaching if desired, to impregnate wood to reduce its shrinkage.ALSO:A mixture of glycols obtained as a distillation residue in the production of ethylene glycol from ethylene oxide and water is purified by diluting with water and removing the impurities which separate, and may then be used to impregnate fine wood to reduce shrinkage and prevent the formation of checks.  The glycol mixture, which has a dark brown colour, may be bleached before use e.g. with hydrogen peroxide and may be used in association with a plastic binding agent, e.g. a phenol-formaldehyde or urea-formaldehyde resin.

Abstract: COMPOSITIONS AND METHODS FOR RETARDING THE        EFFECTS OF AGING OF THE SKIN          Abstract of the disclosure Various effects of photo-aging (sundamage) of the skin including impairment of the differentiation of epidermal epithelial cells, loss of collagen fibers, abnormal changes in the elastic fibers, and deterioration of small blood vessels in the dermis of the skin are retarded by applying topically to the epidermis of the skin in a program of maintenance therapy effective amounts of vitamin A acid (tretinoin) such that epithelial growths are substantially reduced and prevented, and the skin substantially regains and maintains its firmness, turgor and elasticity.  Moreover, with persistent treatment dermal blood cells and vessels increase and the epidermis and dermis thicken, resulting in improved ability of the skin to sense, resist and recover from irritation or injury.  Further, hyperpigmentation, lines and wrinkles due to aging are reduced and prevented.  The treatment is particularly useful for human facial skin and preferably applied in an emollient vehicle in sub-irritating doses.

Title: Magnetic recording and reproducing device
Inventor: IMANISHI KIYOKAZU
IPC: G11B17/32
Filed: 1986-09-02
Granted: 1991-06-11
Abstract: Abstract:      A magnetic recording and/or reproducing device for recording information on a disc-like magnetic recording medium and/or reproducing the information from it, has a pair of magnetic head members each composed of a mag-netic head chip and a slide pad for slidably holding the disc-like medium on both its surfaces between the pair of magnetic head members with a predetermined contact pressure.  The slide pad surrounds the magnetic head chip, and a top portion of the magnetic head chip pro-trudes by a predetermined amount from a sliding contact surface between the slide pad and the disc-like medium. The arrangement enables the disc-like medium to be held steadily in contact with the magnetic head chips, since the slide pads act primarily to minimize warp of the disc-like medium and any deformation of such medium that would result from a deviation in position of one or both of the magnetic head members relative to the medium. The increased flatness and accuracy of orientation of the medium enables a higher recording density to be used.

Granted: 1990-10-16
Abstract: Abstract of the Disclosure A method of operating a computer system is disclosed that facilitates the creation and testing of application system software by utilizing an autonomous environment to emulate the application system environment.          The emulation environment allows the user to call into view sequences of standard input-output (I/O) screen format pairs normally used to submit information to and receive information from the application system.  In the emulation mode, these screens are prepared off-line and stored until the user desires to exercise the application system.  Each input format is filled with information that will serve as actual input to the application system when it is exercised.  Each output format is filled with information that comprises expected results when the application system is actually exercised.  The expected results are compared to actual results after execution of each I/O pair and further application system processing is controlled by the comparison results.  The stand-alone emulation environment provides editing and control routines and library functions to aid the user in defining and modifying the I/O sequences.

Title: Explosive powder charge operated fastening member driving tool
Inventor: GASSNER THEO
IPC: B25C1/18
Filed: 1987-02-26
Granted: 1991-02-12
Abstract: ABSTRACT         An explosive powder charge operated fastening member driving tool has a muzzle part which can be locked within and released and removed from the tool housing by rotational movement and axial movement relative to the housing.  When the tool is not ready to be fired, a contact pressure sensor projects from the front end of the muzzle part.  By pressing the sensor opposite to the firing direction it comprises a firing mechanism spring and the tool is ready to be fired.  Stop elements are provided on the muzzle part and stop surfaces are located on the tool housing.          When the muzzle part is in the unlocked condition, the stop elements can abut the stop surfaces and block the displacement of the contact pressure sensor preventing it from compressing the firing spring mechanism so that the driving tool cannot be placed in the ready-to-fire condition.
